DEFINITION : A function is continuous at a point ‘ a’ if ) ( ) ( lim a f x f a

Unformatted text preview: x = → Notice this is continuity at a single point. ONE point. If we wish to say a function is continuous over an entire interval of values, it must be continuous at each and every point in that interval.
